Question

___________ is used to obtain a uniform mold density in squeezer machine.

(a) Sand paper

(b) Flat plate

(c) Rubber

(d) Carbon

I had been asked this question in an interview.

My doubt is from Moulding Machines in chapter Moulding Machines & Special Moulding Processes of Foundry and Forging

Answer 1

Correct answer is (c) Rubber

The explanation is: In the squeezer machine, squeezing a flat plate produces non-uniform sand density and mold softness, whereas rubber diaphragm squeezing distributes squeeze molding forces more uniformly and thus a uniform mold density is obtained.
